The oil industry takes care of oil’s exploration, extraction, refining and transport. This industry is vital to many others and to keep the industrial area working as it does these days.
Due the hard conditions required to fulfill the different industrial requirements the expectation putted on the materials is also very high. The rigor of the inspection processes has the highest standards, that is why the equipment used for the non-destructive testing must be the best.
Corrosion is one of the biggest problems on the oil industry. The right inspection assures the processes reliability.
Inspection trough corrosion mapping has turned into one of the most used inspection procedures because is easy to use, it optimizes the procedure and the results reliability.
The isolation in the oil industry many times is a need for certain applications. The issue that the isolation carries is that if the moisture penetrates in combination with high temperatures, corrosion is generated.
This is why inspecting pipes is so important and conventional methods of inspection like ultrasound are an option but they’re a great investment because it requires the removal of the isolation layer to do the inspection and afterwards it has to be put back again.
There is a more efficient solution were the isolation layer doesn’t have to be removed, the Pulsed Eddy Current Technique. Where it can inspect the pipe despite the fact that the isolation is on.
Storage tanks are immovable components found in oil plants. These components must be inspected with equipment that offers the higher efficiency because the time invested in those inspections is longer due to the tanks dimensions.
There are two critical zones that must be inspected. The first is the tank floor, it is recommended to make an inspection using an MFL system to locate the corroded areas and then a detailed inspection of that area with an ultrasound system.
The second critical zone are the tank walls. For this inspection it is recommended to use an ultrasonic system that can generate sweeps, therefore the equipment to be used would be one with a magnetic wheel system that can move up and down the walls facilitating the inspection, avoiding the scaffolding bodies around the tanks.
